create application examination
create application examination <application name> [ip-protocol <number> |
[tcp-port | udp-port] <number> match [source-only | dest-only |
source-or-dest] ] [<Ingress QOS profile> | none] precedence <(1-65000)>
Description
Configures ingress queue classification based on application QoS.
Syntax Description
Default
None
Usage Guidelines
This command configures ingress queue classification based on application QoS (IP protocol number,
TCP ports, or UDP ports). This command is similar to the existing
configure diffserv examination
except that it has more arguments and can overlap on the same ports, so an application name is used to
identify each rule. The
none
instead of IQoS profile means that AQoS is not used for queue
classification for the matching packets and the next lower ingress qostype priority (queue classification)
is used. Precedence is required, since a match on multiple rules is possible. Up to 1,000 application
examination rules can be created.
Example
The following command creates an application examination rule, TCP20, which will assign ingress TCP
traffic with a destination port number of 20 to the ingress qosprofile IQP3 with a precedence value of
100:
create application examination TCP20 tcp-port 20 match dest-only iqp3 precedence 100
application name Specifies the name string to associate with this rule.
ip-protocol Specifies that a match will be attempted on the IP protocol number in the received packets.
tcp-port Specifies that a match will be attempted on the TCP port numbers in the received packets.
udp-port Specifies that a match will be attempted on the UDP port numbers in the received packets.
source-only Specifies that when doing TCP or UDP comparisons, only source port numbers will be
compared.
dest-only Specifies that when doing TCP or UDP comparisons, only destination port numbers will be
compared.
source-or-dest Specifies that when doing TCP or UDP comparisons, both source and destination port
numbers will be compared. The match is successful if either source or destination port
equals the specified port number.
Ingress QoS profile Specifies an ingress QoS profile name to associate with any ingress packets matching this
rule.
none Traffic matching this rule will not be associated with any ingress queue based on application
examination.
precedence Specifies the precedence value for this rule. If an incoming packets matches multiple rules,
the precedence number is used to determine which rule to apply (lower number = higher
precedence).
